Im running one hx1000 and one rx850w for a 6 vega rig no problem. There is enough pci-e connectors, some cards will need to use the daisy chain 2x6+2pin pci-e cables for power. Im sure the hx1000w has 5 pci-e terminals and comes with 2x 8pin-6+2pin and 2x 8pin-2x6+2pin cables

Gpus are still massively overpriced in the UK too, not much 2nd hand gpus anywhere except ebay. Most are still about 50% higher than they should be. 2nd hand vegas are selling for £700.

Have you tried a cmos reset? its a pain to reinstall windows again but ive found its usually quicker to start again from scratch than troubleshoot problems on a new build. Also if you need to change bios settings i would do it before adding multiple gpus. That seemed to be my problem, but different mobo and gpus

I think a better way of working it out would be to use an average daily profit to work out what would be more profitable rather than an arbitrary number of coins that way it could be used for multiple coins, so in this scenario for the mining option it would be $15 per day @ same cost. So anything over $11.50 per day profit better to mine than buy, and you will also have a mining rig left over at the end of the year to continue mining with. But as you said with the other variables to factor in its near impossible to predict coin prices or difficulty increases. 

Getting rich in crypto is possible but not quickly, if your lucky and find coins outside the top 100 with a good team, the coin has a use and isnt just a copy of other coins already available then its more than possible. However any coin that has guaranteed returns should be avoided at all costs. Bitconnect being the example, although anyone caught up in the bitconnect scam was blinded by greed and shouldve taken the time to thin about here the 'profit' was going to come from.

Yeah minexmr is a pool. Thanks for the info I was pretty sure the hashrate shouldn't be dropping and from what I can tell the payouts are close to what the calculator predicts. I just found it strange that for months it showed the accurate speed ( average ) but now it's a good bit out

My hashrate on xmr-stak is steady at 11.5k h/s 6x vegas but on minexmr it has been steadily decreasing for the last couple weeks. The difficulty chart shows that the difficulty has been increasing but does this explain the drop in hashrate and if it does shouldn't the hashrate on the miner be dropping too?

I mine in the UK was lucky enough to get some vegas when the were first released and am looking to build another miner sometime soon so have been looking at what cards to go with. First choice is AMD or NVIDIA, from my experience to get best performance from AMD cards BIOS modding is usually required whereas NVIDIA cards are good with a bit of tuning so if bios modding isnt your thing then i would go for NVIDIA ( Vegas would still be first choice for me for profitibilty even without bios modding for Monero anyway ). NVIDIA cards are also more profitable over many different algos whereas AMD cards are better for specific coins. With a £5000 budget you could build a miner with any 6 GPUs you like, although maybe possible to build 2 miners one with AMD RX570/580 and the other with 1060 6gb/1070. Be aware tho that the cards i mentioned before will have the least resale value if the time ever come to sell up. A rig with 1080s is likely to be profitable for much longer than rx5xx/gtx1060 and easier to sell. Personally i would stick to 6 cards max per rig to avoid unnecessary headaches and minimise downtime ( first time round anyway ).


^^This is true in my case, holding wouldve made 10x what i have from mining. Electricity isnt too big an issue though 13p/KWH is manageable

Yeah in currently running one machine still not registered with no issues so far, been running for a couple months now.

I have this problem occasionally too, with the Pro BTC Mb. When this happens the only way I've found to fix it is to use the AMD driver uninstall tool and install them again. Using blockchain drivers windows 10 6x VGA rig

I've bought windows 10 from 3rd party sellers before for about £20 but not from eBay. I've also bought older versions from 3rd party sellers before and never had any issues.

I've read that only 2 connectors are needed to run the custom Vegas the 3rd is only needed for overclocking.

Im running a vega rig and only run 3x vegas per gpu on 850W psus. If you plan to mod the cards to run @180W then you should be ok. My Vega 56s run around 220W mining without modding the cards using blockchain drivers. Personally id keep the 8gb RAM i had issues getting cards to mine at full speeds without it but others have managed it.

Celeron CPU works fine on for me but id agree if you can get an i3 or better for a few extra bucks i found it saves a fair bit of time resetting the miner and wattman when needed.

What kind of frame do you plan to use? My first one was a open DIY with good spacing but when i built one using a bought frame the cards run 20% hotter without some extra fans cos they are a bit closer together.

I have the same motherboard running 4x vega64s and 2 Vega 56. Had a few problems to start off. In the end I had to reset the CMOS jumper and start again. Don't know if it makes a difference but I updated and changed the's the settings in bios before adding any GPUs second time round. First time I had the GPUs installed and had problems installing drivers

Looking at it closer I think there is a piece of wood covering the bottom of the frame in the pictures. Look at the bottom right side where the inside frame should be looks covered by the wood in the top picture.

I've been using minexmr since I started mining monero never had any issues with the site

Use the -G command to select the Vega only, -G 0/1/2/3 depending on what number the miner gives to the cards. So run the miner with all cards to figure out what what one is the Vega then select that one alone.

Question for anyone pushing over 1950h/s with the Vega 64s. How stable are your card clocks in Wattman while.mining? Also could bouncing clocks damage the card/reduce life of card. I feel that if the clocks hold steady mining when using standard settings then it should be the same when over/underclock get but this might not be true.

The best settings I've found to keep stable clocks are 1100/1100 core 1025 mem -10% power temp 62 max. Reducing power any more causes bouncing clocks as does increasing mem. No Bois mod cards using 215w each.

On a different point I've found that setting core clocks manually at 1100/1100 or even 1200/1200 let's the cards run much cooler than using the % slider to a similar level.

I'd start by dialling back the overclocking on all cards to 1080 and see if they all hold at that, then one by one increase them to see if they hold 1100. Personally I prefer running all cards a little below the max, mixed opinions on this but for 24/7 running I don't think it's wise to push the cards especially reference Vegas with the pissy drivers and high temps.

For me card temps weren't related to the GPU COMPUTE ERROR, as long as the cards were clocked stable high temps only reduced mining speed in my experience.


Start by dialling back the overclock/undervolt in that card. Not all cards can hold the same speeds/voltages. One of mine always runs 10% slower than the rest. I change the tach lights to blue on the weaker card/s that way when new drivers are installed or different mining software used and the order gets messed up you can track the weaker card easily

You will need 8gb of ram to activate hbcc using Wattman. I've heard it can be done by disabling each card in device manager then activating again but I haven't tried thisywelf as I had bought an extra 4gb before that fix was found. Still not attempted the reg mod for the power consumption yet. Currently running 4x Vega 64s at 900W 1950h/s per card
